Figure 2

Example of fixations performed with the eccentric and the central PRLs to read "dorénavant". Successive fixations performed with the eccentric (dashed red) and the central PRLs (plain red) are shown for patient CN (right eye) while reading the word "dorénavant" (bold characters). Character size was 0.9 logMAR, i.e., 0.6° of visual angle on average. The time (hour:minute:second.frame) and the starting frame number of the picture ("Image status: Available") are shown beneath each image. The word appeared on an eccentric position (image 1) and was progressively (image 2) brought adjacent to the lower border of the retinal lesion where is located the eccentric PRL (image 3). A further saccade positioned the word adjacent to the central PRL (image 4), and into it (image 5). Finally several horizontal saccades along the word completed deciphering the word (images 6, 7). Note that this figure represents retinal pictures as seen through the SLO.
